- PURPOSE: Acute polymorphic psychotic disorder (APPD) without symptoms of schizophrenia is a serious psychiatric condition. APPD can be effectively treated with electroconvulsive therapy (ECT), but little is known about relapse prevention after ECT for APPD.MATERIALS AND METHODS: This was a retrospective register-based study conducted with 97 patients with APPD (ICD-10 diagnosis F23.0). We estimated the rates of readmission and suicide, and the prognostic factors of these outcomes after ECT. We combined data from several national Swedish registers and used Cox's regression analysis to identify demographic factors, disease characteristics, and relapse preventive treatments that predicted time to readmission or suicide (relapse). Data registered between 2011 and 2016 were used in the study.RESULTS: Twenty percent of cases relapsed within a year. Thereafter, relapse rate was low. Two cases died during follow-up, whereof one by suicide. Anxiolytic treatment, lamotrigine treatment, and having more than four previous psychiatric hospital admissions were associated with shorter time to relapse. The most robust of these associations was between anxiolytics and relapse risk.CONCLUSIONS: The first year after discharge from APPD is the period associated with the highest risk of relapse. Having many previous admissions was associated to relapse risk after ECT for APPD. The associations between anxiolytics, lamotrigine, and relapse are uncertain and might be influenced by indication bias.

- Background: Response rates after and tolerability of electroconvulsive therapy (ECT) in depressive disorders with psychiatric comorbidity are uncertain.Methods: Data on patients with a depressive episode and a first course of ECT were collected from the Swedish National Quality Register for ECT. Logistic regression analyses, adjusted for gender, age, and depressive episode severity, were used to compare patients with and without comorbidity. The clinical response assessment Clinical Global Impression - Improvement Scale was used in 4413 patients and the memory item from the Comprehensive Psychiatric Rating Scale was used for subjective memory impairment rating after ECT in 3497 patients.Results: In patients with depressive disorder and comorbid personality disorder or anxiety disorder, 62.7% and 73.5%, respectively, responded after ECT compared with 84.9% in patients without comorbidity [adjusted odds ratio (aOR) 0.43, 95% confidence interval (CI) 0.34-0.55, and aOR 0.61, 95% CI 0.51-0.73, respectively]. The proportion of responding patients with comorbid alcohol use disorder was 77.1%, which was not significantly different from that in patients without comorbidity (aOR 0.75, 95% CI 0.57-1.01). The impact of comorbidity decreased with higher age and depressive episode severity. Subjective ratings of memory impairment did not differ between patients with and without comorbidity.Limitations: Observational non-validated clinical data.Conclusions: The response rate after ECT in depression may be lower with concurrent personality disorder and anxiety disorder; however, the majority still respond to ECT. This implies that psychiatric comorbidity should not exclude patients from ECT.
